The details of construction and. arrangzements which I have herein shownand described mafiv be varied without affecting my invention, Vand hencelimited to such specific form of switch.

Having thus described my invention, what I claim as new and desiretosecure by Letters Patent is zv 1. ln a. switch of the characterdescribed,

l )l M designate the 1 the battery circuit. which are i do not wish tobe the combination of a movable shaft, two

independent switch members loosel)v mounted on said yshaft. and clutchmeans whereb)v movement of said shaft in one direction will move one ofsaid members', and movement of the shaft in the opposite direction willturn the other of said members.

2. In a switch of the character described, the combination of a movableshaft, two dependentl switch members loosely mounted on said shaft, contact devices cl3-operating with the said members whereby the circuitthrough one member is normally closed and the circuit through the othermember is normally open7 and vices carried by. said stationaryconducting parts.

f carriers to establish or co-operatin br clutch deshaft and members.

whereby movement of said shaft in one direction from the normal positionwill close the open circuit without openingr the closed circuit, andwhereb)Y movement in the opposite direction from said normal positionwill open the closed circuit without closing the open 1 circuit.

in a switchof the character described, the combination of a shaft, aclutch member co-operate with said clutch connected to one of the saidmembers and acting to resisty movement thereof and to effect its returnmovement7 and a spring connected to the other member and forming a locktherefor, and also an actuating?y means.

4. In a switch of the character described, a movable shaft. having theswitch membersy D and E loosel)v mounted thereon., and provided withclutch hubs. a clutch member secured to said shaftbetwecn thc members Dand E and arranged to operativelv engage the said members by reversemovements of the said shaft. a rctuiningspring connected to the memberl), and the dog H and spring;y l.

' connected to the member l), substantiallyr as described.

5. ln a device of the character described. a plurality of movableconducting parts, indepei'idently movable carriers for said parts, anda` coininon means 'for independentl;v moving said break the connectionsof the relatively movable and stationary' conductive parts.

6. In a device of the class described. stas tionaiwv conductingy parts.a plurality of mov able conducting parts, independenthY movable carriersfor said movable parts, a concealing structure for said conductingVpai-ts. and means extending without the conccaliir;I

structure for independently moving said cait riers to establish or breakthe electrical connectionof the relativelv movable and st atioi.- aryconductingr parts. in testimony whereof,I have allixed mi signature inpresence of two witnesses YILLIAM MUIYON BRO. N".
